The black spoke earnestly, and his eyes glistened.

‘I don’t see much chance of making a fortune or finding riches in a desert,’ said Edgar. ‘Where is this wonderful cave that contains so much wealth?’

‘Many miles,’ said Yacka; ‘over Great Desert in Northern Territory. It is not all sand. No white man has been there; but Yacka has, and knows there is grass and water, and food, plenty food.’

‘Are you certain no white man has ever been there?’ asked Edgar.

Yacka hesitated a few moments, and then said:

‘No white man.’

‘And no white woman?’ laughed Edgar, who noticed the stress Yacka laid on man.

Yacka sprang to his feet, and waved his arms about wildly.

‘Come and see!’ he cried. ‘Come to the White Spirit’s Cave! I am the son of Enooma!’
